Assuming you have legal access to the file, here is a strategic study plan to move from a "pass" to an "A+."
The criteria necessary for a signal to have a valid Fourier series. Chapter 4: Fourier Transform (FT)
Excellent for self-practice. You can learn how to solve any standard problem just by mimicking the solved examples.
A huge number of fully solved examples help students understand how to apply theoretical concepts to solve numerical problems. Signals And Systems By Anand Kumar.pdf
Convolution can be mathematically abstract. Practice the "flip and slide" graphical method to build visual intuition.
Continuous-time vs. discrete-time, periodic vs. aperiodic, energy vs. power, and deterministic vs. random signals.
While classics like Oppenheim and Willsky are often cited as the gold standard, many students—especially those preparing for competitive exams like GATE or university semester exams—turn to a different name: Assuming you have legal access to the file,
The z-domain counterpart to the Laplace transform.

Kumar’s writing style is characterized by: A huge number of fully solved examples help
Implementing noise cancellation, compression (MP3/JPEG), and equalization. How to Study from This Book Effectively
Do not jump straight to the math. Read the introductory text of each chapter to understand why a particular transform (like Fourier or Laplace) is needed.
This direct, plug-and-chug method is why students hunt for the at 2 AM before an exam.
Start with the solved examples provided within the text. Once you understand the methodology, challenge yourself with the unsolved exercises at the end of the chapter.
Converting differential equations into easily solvable algebraic equations.
